JAMES L. PERRY, OF BERLIN, WISCONSIN, ASSIGNOR OF ONE-HALF TO CHARLES A.MATHER, OF SAME PLACE.

WOOD-POLISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 240,179, dated April12, 1881.

Application filed October 2, 1880.

To all whom it may concern:

Be it known that I, JAMES L. PERRY, of Berlin, in the county of GreenLake and State of Wisconsin, have invented a new and valuableImprovement in Wood-Polishing Machines; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure l of the drawings is a longitudinal section of the device. Fig. 2is a' plan view. Fig. 3 is an enlarged view of the brush. Figs. 4 and 5are enlarged sectional details of the rollers.

This invention relates to wood-polishin g machines. It has for itsobject the construction of a device whereby plane surfaces of wood maybepolished and deprived of all superficial fibers in such a manner as toeffect an exact and perfect finish.

The invention consists in the combination of rotary reducers, consistingof polishingrollers and a finishing-brush, the construction of therollers, the relative position and adj ustability of the brush, andother details, all as hereinafter specified.

In the annexed drawings, A is a frame suitably constructed toaccommodate the machinery.

B is the top, consisting of the receiving-table M, depositing-table N,and the cross-barb and bearing b, and having the openings D E F. To eachend of the openings D E is located a standard, D E, having a slot, d e,in which slots are seated the journal ends of the presserrolls D E",adjustable therein by blocks and screws. Pivoted near the bottom of eachof said standards D E is a pair of sector-hangers, D E, having neartheir outer edges the grooves d e. Seated in said grooves d e are thefeed-rollers d d e e, the rollers 61' 0 being adjustably held by springpresser-blocks and screws.

Immediately under opening D, with its peripheryprojectingabove the faceof said opening, is hung a roller, H, upon shaft H. In a similarposition with regard to opening E is hung, upon shaft 1, a roller, I.Below said (No model.)

rollers are located troughs K K, having bottom outlets, k k.

Below opening F is hung, upon shaft L, a brush, L.

The construction and operation of the rollers and brush is this:

The body of roller H has in its surface longitudinal oblique grooves h,and between said grooves, and extending to the edges thereof, aresections of carpet h and paper felting h. Covering such sections andsurrounding the roller is a covering, first, of rubber h, and thensand-paper h, said rubber and paper being held in place by strips H,which press them into the grooves h. This kind of roller operates verywell where a high degree of pol-.

of rubber and sand-paper; but the sections inside are differently madeup. In said Fig. 5, I is the body of the roller, having grooves 1'.Between said grooves, and reaching to edges thereof, are the sections,which are made ofthe following material: Next the body portion 1 is alayer of Brussels carpet, i, with the face outward, then a layer ofpaper felting, f, and outside this a layer of Brussels carpet, g, withthe face inward. Outside these are fastened the rubber 7c and sand-paperl by the strips P, secured in grooves "6. By this construction the loopsof the carpet are turned toward each other, with the paper feltingbetween, whereby a line degree of elasticity is given to roller, and theedges l I meet the work with a smooth, gradual yielding pressure, andthe fibers are neatly reduced and an exact polish given to the surface.

The finishing-brush L is attached to the table N by hangers R, thejournals of the brush being inserted in blocks 1", which slide up anddown in slots 1" of hangers R, and are ad justed therein by screw r. Theposition of this brush in relation to the frame is such that theperiphery of the brush is on a line with the tops of bearings b and n,which said bearings act to support the work as it comes fromthe rollers,by which construction the tips of the bristles alone act upon the workand remove the fine fibers which may have been left by the rollers. Itwill be seen that this whipping action of the tips of the bristlesproduces this result, for if the sides of the bristles struck they wouldmerely sweep off the dust, but would not affect the fiberswith the sameprecision and consequent finish as the tips.

The depositing-table N swings upon the pin 0, which enters slots *r" incurved arms B. By this arrangement table N and brush L can be swungaside and the roller I readily reached.

The work is presented to the machine upon table M, and is fed throughthefeed-rollers to roller H, from thence to roller I, and from this to L,and is then received upon the table N. The two rollers H and I and thebrush L are run each independent of the others and at different rates ofspeed, the roller H and brush L moving in one direction, meeting thework, and roller I moving in the opposite direction, moving with thework. By this device the board is first caught by roller H, and thefibers are dressed off one way, and then the roller I cuts them theother way, and the brush L, by its whipping action, removes any finefibers or filaments which may have been left by the rollers. It willthus be seen that the action of these reducers, moving successively inopposite directions and at different rates of speed,

is such that each succeeding reducer operates to remedy inaccuracy inthe preceding one, by which construction and arrangement work presentedto the machine has all superficial fibers removed and receives a highdegree of polish.

I claim 1. In a wood-polishing machine, the combination of the twopolishing-rollers, the finishing-brush, and means, substantially asdescribed, for adjusting the brush with its tips just in contact withthe object to be polished, as set forth.

2. A roller having a body portion, fillingsections composed of twopieces of Brussels carpet, and an intermediate layer of paper felting,the faces of the two pieces of carpet being turned toward each other,with their loops bearing against the paper felting and the cox'erings ofrubber and sand-paper.

3. The frame carrying the polishing-rollers, in combination with thetable carrying the brush and hinged to the frame.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JAMES L. PERRY.
